Zmqnumpy module implements a series of functions used to exchange
numpy ndarrays between U{zeromq<http://www.zeromq.org>} sockets.
Serializtion of numpy arrays happens using the numpy.ndarray.tostring method
which preserves portability to standard C binary format,
enabling data exchange with different programming languages.
A very simple protocol is defined in order to exchange array data, the
multipart messages will be composed of:

identifier string name

the numpy array element type (dtype) in its string representation

numpy array shape encoded as a binary numpy.int32 array

the array data encoded as string using numpy.ndarray.tostring()

This protocol guarantees that numpy array can be carried around and
recostructed uniquely without errors on both ends of a connected pair enabling
an efficient interchange of data between processes and nodes.
